Put your hand 3/4 of an inch above the flame of a candle. Immediately, it hurts. Don’t move. Watch the burned wax turn black to paraffin. Its melting point is only 99 Fahrenheit. less than half a degree above your “normal.” More like urine than lava. Then, it stops burning. Black tendrils. It turns out what hurts is subjective. This is a metaphor.
